2.Build or buy the book box. Boxes start at $175 on littlefreelibrary.org; you can register at the same time for free. If you want to build one yourself, use whatever materials you like — recycled wood, old mailboxes. Most people use plywood and Plexiglas. Find tons of great tips, resources, and samples online as well.

4. Install your library. The website includes instructions for mounting. If you’re hoping to set up somewhere other than your property, check on permits. You can also ask your child’s principal about getting the school involved. Building a series of book boxes could be a great project for students!
